The OEF is defined as the ratio of oxygen used by the brain to oxygen delivered by flowing blood and is remarkably uniform in the awake but resting state (e.g., lying quietly with eyes closed).  ...  We used quantitative metabolic and circulatory measurements from positron-emission tomography to obtain the OEF regionally throughout the brain. Areas of activation were conspicuous by their absence.  ...  The brain mean OEF was chosen as the baseline level of activity on the basis of its general uniformity in the eyes closed, resting state.  ...
